It is recorded that Blackbeard had plans for governing a secluded egalitarian colony before he was killed. This series is based on those plans that never materialized.
Although he was one of the most accomplished and feared pirates of his era, there is no recorded instance of Blackbeard personally killing anyone before his final battle.
Hugh Laurie was in negotiations to play Blackbeard. The role eventually went to Malkovich.
The show was to be a part of NBC's mid-season schedule, but was later pushed to summer.
